Health Claims on Food Labels

When launching or scaling a food brand, communicating the health benefits of your product on the packaging is often a primary marketing goal. However, in my practice as a registered nutritionist working with both individual clients and commercial food businesses, I frequently see well-intentioned brand owners make claims that unwittingly breach UK regulations. The UK regulatory landscape surrounding food claims is strict, and getting it wrong can lead to enforcement action from Trading Standards or formal rulings from the Advertising Standards Authority (ASA).

Understanding what you can and cannot say legally on packaging, e-commerce websites, and social media is essential for building a credible brand. Following the UK's departure from the EU, nutrition and health claims made on commercial food products in England, Scotland, and Wales are governed by the Great Britain Nutrition and Health Claims Register (GB NHCR).* Here is a clear breakdown of how to navigate these rules legally while keeping your product messaging compelling.

Nutrition Claims vs Health Claims: Knowing the Difference

To stay compliant, you must first distinguish between a nutrition claim and a health claim. A nutrition claim states, suggests, or implies that a food has particular beneficial nutritional properties due to the energy or nutrients it contains or does not contain. Examples include "high in fibre", "low fat", or "source of protein". These claims are strictly defined in law, meaning you cannot invent your own terms like "protein rich" or "packed with fibre" unless the product meets the explicit legal threshold defined in the regulation.

A health claim, by contrast, states, suggests, or implies that a relationship exists between a food category, a food, or one of its constituents and health. For instance, stating that "vitamin C contributes to the normal function of the immune system" is an authorised health claim. You cannot simply claim that a product "boosts immunity" or "cures fatigue" without using the precise, authorised wording or a approved variation permitted by the Great Britain NHCR.

General Health Claims and the Wording Trap

Many food businesses want to use sweeping, consumer-friendly statements like "supports gut health", "superfood", or "detoxifying". Under UK law, broad statements that refer to general, non-specific benefits of a food for overall good health or health-related well-being are classed as general health claims. These general claims are only legal if they are accompanied by a specific, authorised health claim from the official GB register.

For example, if you wish to state on your packaging that a product "supports your digestive wellness", you must pair that statement with an authorised specific health claim on the same label, such as a claim regarding calcium contributing to the normal function of digestive enzymes, or oat grain fibre contributing to an increase in faecal bulk. If you are developing products that target metabolic health or blood sugar management, it is crucial to align your packaging with compliant claims. in my work with individuals, such as clients managing diabetes, I see how confusing misleading packaging can be. If you live with a medical condition such as diabetes or insulin resistance, I work alongside your doctor so that any significant dietary change fits safely with your medical care.

Medical Claims Are Completely Prohibited on Food

The most severe compliance error a food business can make is applying a medicinal claim to a food product. UK food law explicitly prohibits any food label or marketing material from claiming that a food can prevent, treat, or cure a human disease. Phrases such as "lowers risk of diabetes", "cures joint pain", or "anti-inflammatory protection against heart disease" are illegal on food products.

Even reduction of disease risk claims, which are a specialised category of health claims, carry very precise authorised text and stringent criteria. If you want to highlight the broader nutritional value of your range, reviewing our food labelling regulations guide will give you a comprehensive overview of general mandatory labelling requirements beyond claims.

Practical Steps for Food Brands to Remain Compliant

If you are reviewing your packaging artwork, launching a new product line, or refining your digital marketing claims, implementing a structured verification strategy is crucial. I advise food brands to follow this clear process before printing labels or publishing campaigns:

• Audit your compositional data: Ensure you have reliable, accredited lab testing or robust calculated nutritional data that proves your product hits the exact numerical threshold required for a nutrition claim, such as 6g of fibre per 100g for a "high fibre" claim.
• Check the GB Register: Verify that any specific health claim you intend to use appears on the Great Britain NHCR and that your product contains a significant amount of the relevant nutrient.
• Qualify general claims: If using broad terms like "gut-friendly" or "brain food", ensure an authorised claim is prominently displayed alongside it with an explicit link, such as an asterisk.
• Review all marketing channels: Remember that rules apply to social media posts, influencer collaborations, point-of-sale materials, and website copy, not just the physical packaging.
• Plan reformulations early: If your product falls short of a claim threshold, consider early recipe reformulation to achieve the necessary nutrient levels legally.

Balancing Commercial Appeal and Regulatory Compliance

Achieving regulatory compliance does not mean your packaging has to read like an academic paper. Brands can create engaging, highly commercial messaging while remaining entirely compliant with Trading Standards and the ASA. Integrating compliant claims into your wider business model is explored further in our guide to nutrition strategy for food businesses, as well as our breakdown of HFSS regulations for retail placement.

Navigating the line between compelling brand messaging and strict legal compliance gets tricky the moment you try rewording an authorised GB Register claim to fit a catchy front-of-pack design without accidentally altering its legal meaning. Whether you are a food business owner needing precise recipe audits and verified packaging copy to protect against Trading Standards challenges, or an individual wanting to cut through marketing buzzwords on everyday food labels, expert support bridges that gap.
